Rose, who previously dated Kanye West, tweeted a photo of her engagement ring with the message "He has made me the Happiest Woman in the World!!!!"

The couple hinted at the Grammys that marriage was in their future, but the timing had to be perfect. "We're just taking our time," Rose said in red carpet interview with E! "Whenever he wants to propose, that's when it will happen."

Khalifa also tweeted about the engagement news, saying "She said yes!" and "Love is everywhere." Rose and Khalifa have been together for one year.
